No, you should not use regular spray paint on RC car bodies. RC car bodies are typically made from polycarbonate (a type of durable, flexible plastic), which requires specialized paints that can bend without cracking. Regular spray paint is designed for rigid surfaces like metal or wood and lacks the flexibility needed for RC bodies, leading to issues like poor adhesion, peeling, or chipping upon impact. Instead, use paints specifically formulated for polycarbonate, such as those labeled for RC use, which contain flex agents to maintain durability.
The key difference lies in the paint's composition. Regular spray paint often uses hardeners that can make the polycarbonate brittle, while RC-specific paints are engineered to remain elastic. For example, when an RC car crashes or flexes during high-speed turns, the body needs to absorb shock without the paint flaking off. Proper surface preparation is also crucial: always clean the body with soap and water, lightly sand it for better grip, and apply a polycarbonate-compatible primer if needed.
Here's a comparison of paint types based on common user experiences and industry standards:
| Paint Type | Flexibility | Adhesion to Polycarbonate | Durability | Cost per Can (USD) | Recommended for RC? |
|---|
| Regular Spray Paint | Low | Poor | Low | $5 - $10 | No |
| RC-Specific Paint | High | Excellent | High | $10 - $20 | Yes |
| Automotive Touch-Up Paint | Medium | Fair | Medium | $15 - $30 | Not Ideal |
| Acrylic Model Paint | Low | Fair | Low | $8 - $15 | No |
| Polycarbonate Primer | N/A | Excellent | High | $10 - $18 | Recommended as Base |
For best results, apply thin, even coats in a well-ventilated area, allowing each layer to dry fully. This approach ensures a professional finish that withstands the rigors of racing or bashing. If you're on a budget, investing in RC-specific paint saves money long-term by avoiding redos.
